A micro-tiller module that is releasibly engageable with a hand drill can include a gear box assembly, first and second tilling wheel assemblies, and a stabilizer fork. The gear box assembly can include a housing, an input shaft extending along an input shaft axis, first and second output shafts, and a plurality of gears. The external end of the input shaft is configured to be releasibly engageable with a chuck of the hand drill. The tilling wheel assemblies can be respectively mounted to the output shafts. The stabilizer fork can extend from a base end fixed to the housing, along a stabilizer axis transverse to the input shaft axis, to a distal end from which first and second tines project. Each of the tines can extend further along the input shaft axis than transverse to the input shaft axis.
